IMPROVEMENT IN C'OMBINED'URN AND WATER-BOTTOMS.

Specification forming part of Letters Patent No. 210,207, dated November 26, 1878; application filed October 27, 1877.

- zontal section; Fig. 3, a side view.

My invention relates to certain improvements in that class of urns which are provided with a hollow chamber beneath the bottom, which is designed to be filled with water.

The-improvement consists in making the urn and water-chamber of stoneware, and in one piece, and in extending up, upon the outside of the urn, from the water-chamber, two tubes,

which are constructed of the same material as the urn, and serve, the one to allow the escape of air when water is 'being introduced through the other, and vice versa, so that the filling and emptying of the water-chamber may be easily eflected.

In the drawing, .A represents an urn, made of stoneware.- B is the bottom of the urn, and B a second lower bottom, which, together with the bottom B-and the extended side walls of the urn, form aclosed chamber,,which con-' stitutes the water-bottom. G O are the two tubes, arranged side by side, as shown, or upon opposite sides of the urn, if desired, and formed upon the body of the urn. These tubes communicate below with the water-bottom, and are extended upwardly upon the outside of the urn, terminating in flaring months, for facility in introducing the water. gree of upward extension is not limited or fixed at any particular point; but the object of the said extension is to prevent the water in The dethe water-bottom from spilling or boiling over through the tubes, and said tubes should therefore be extended a sufficient distance to obviate this.

at a uniform heat without burning or destroying the flavor of the same, when a constant source of heat is employed beneath, and which serves also to keep the contents of the urn hot for a longer time after the application of heat is discontinued.

I am aware that it is not new to extend a single tube up from the water-bottom and upon the outside of a sheet metal coffee-pot, and I therefore only claim a stoneware receptacle havingtwo such tubes formed upon the same, and in one homogeneous piece therewith.

Having thus described my invention, what I claim as new is- A stoneware receptacle for beverages provided with a water-bottom having communication with two tubes formed upon the out-.

side of said urn into one homogeneous piece therewith, substantially as described.

The above specification of my invention signed by me this 7th day of September, 1877.
